Toggle: Swain transforms into the form of a raven. During this time, up to 3 lesser ravens strike out at nearby enemies each second, prioritizing champions. Each raven deals 50/70/90 (+0.2*AP) magic damage and heals Swain for 75% of the damage dealt against champions, and 25% against minions. The cost to sustain Ravenous Flock increases by 5/6/7 Mana each second.
